When I try to create a Query in BASE with Wizard it will not save when I hit Finish.When I do create it in Design it does save BUT it crashes the program the instant I try to run it.When I hit recover the program recovers well BUT WITHOUT the Query listed.

IS THERE A COMPATIBILITY ISSUE BETWEEN OFFICE 4.1.3 AND macOS 10.13.1?

Hard to say. If your base document does not contain confidential info (or you can remove it), please upload it so that other can test it as well. You can post your query in the document or separated in this thread.

Your query is wrong. You GROUP BY on "Type", but did not apply a aggregate on "Name". When you e.g. replace "Name" by COUNT(*) AS "Occurrences" your query is OK and should work.

So it looks like there is a stability issue when you have an erroneously query with a GROUP BY.

You might test more queries with errors: E.g use non-existing column name or table name and see it that brings Base down as well.
